Electrical panel
Target Asset
- Electrical panel monitoring, where tracking the consumption of both input and output lines is required.
- Suitable for monitoring scenarios where acquisition of signals from multiple power lines is necessary. With this kit, electrical panels are interfaced using 3 power clamps for the input lines and up to 5 power clamps for the output lines.
- Lines and Panel status can be inferred via power consumption level analysis (thresholds).
Features
- Supports up to 8 channels for reading power clamps to be installed in the electrical panel.
- Features 3 dedicated channels for comprehensive main phase analysis, including general power metrics and an unbalance index.
- Features 5 specialized channels for monitoring sublines, accommodating single-phase monitoring even in cases where the sublines are three-phases.
- Ethernet/Wifi Connectivity
The kit includes:
- 1x 4ZeroBox Lite (DB+AIN)
- 1x 220-24V power supply,
- 3 x 500 Amp Power Clamps
- 5 x 100 Amp Power Clamps
